Abstract

1. Electrical lead accumulator with limited maintenance, comprising in a casing a group formed of positive and negative plates and separators, immersed in the electrolyte, a separator filling the space between a positive and a negative plate, said separator being constituted of a microporous material of unwoven fibres, characterized in that the separator is constituted by one or more layers, the unwoven fibres of which are of a material chosen from glass and the synthetic materials, the pores of the microporous layer(s) having diameters comprised between 100 mu m and 600 mu m.
